Title: Image forming device
Inventor: OKI SHIGERU
IPC: G03G21/00
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To prevent a density sensor from becoming dirty and also prevent carrier deterioration and an image defect by providing a shutter member which covers the detection surface of the density detection sensor and a discriminating means which discriminates its opening/closing state. SOLUTION: An image density detecting means 80b is provided with the shutter member which prevents the detection surface of the sensor from being stained on the photosensitive drum 4K side of the sensor. This shutter member is composed of a cover 86 which has an opening 85a only in front of the detection surface of the sensor and a moving member 87 which is provided more on the sensor side than the cover 86 and moves by a solenoid in the axial direction of the photosensitive drum 4k and has an opening 85b of the same size with the cover 86. Further, the ratio of the initial value of a drum surface reflection output and a value for each copy is used as a coefficient α of window staining to make corrections for the window staining.  Then when this coefficient αhas large variation from a last value (α<=0.9αn-1 ), it is discriminated that the shutter member is closed and the output of the sensor is not correct, so toner supply based upon the detection output is not performed.

Abstract: PURPOSE:To attain the recognition of a transmission state instantly at its own seat by a sender by reporting transmission state information relating to the sent facsimile equipment to the sender by a phone call. CONSTITUTION:The sender sets a transmission original to a facsimile equipment main body 1 and inputs the destination telephone number from a sender subscriber number input section 7 and registers it a sender subscriber number information storage section 3. Then a sender control section 2 dials an incoming subscriber number stored in an incoming subscriber number information storage section 4 for connection and sends an original. When the original is sent normally, the voice representing the arrival is edited by a voice editing 5, when the opposite party does not answer it is edited, and when data is not sent by a fault of transmission, line or equipment. Then the caller control section 2 dials the telephone set stored in the caller subscriber number information storage section 3 to call the caller and the voice edited by the section 5 is sent.

Title: Photosensitive recording sheet housing device of image recording device
Inventor: MATSUMOTO YUMIO
IPC: G03F7/00
Filed: 1987-07-21
Abstract: PURPOSE:To shorten an exposing cycle time by providing an air feed port to one side of a light shielding case, connecting a means for supplying heat insulating air which supplies the heat insulating air to this air feed port and providing a discharge port to the other side of the light shielding case. CONSTITUTION:The warm air near a halogen lamp 5 of a photosensitive recording sheet housing device is sucked from a suction port 14a by the operation of a blower 14 and is delivered from a blow port 14b. This warm air is fed through the air feed port 16a into the light shielding case 1. While the arm air warms a feed roll 2 by passing between a cover 16 and a flange 18a and between a housing 15 and the roll 2, the air flows between a cover 17 and a flange 18b and is discharged from the discharge port 17a. The warm air efficiently heats the roll 2 by smoothly passing the inside of the light shielding 1 along the axial line direction of a roll core 18. The roll 2 is quickly heated up to a prescribed temp. and the exposing cycle time is thus shortened.

Title: Oscillation circuit
Inventor: MATSUOKA TOSHIAKI
IPC: H03K17/95
Filed: 1990-07-10
Abstract: PURPOSE:To exclude trouble caused by the change of an atmospheric temperature by providing a temperature compensating circuit to control loop gain corresponding to the atmospheric temperature. CONSTITUTION:A temperature compensating circuit E is provided to control the loop gain corresponding to the atmospheric temperature. In this case, when amplifying the output of an LC parallel resonance circuit and loading positive feedback to this output, the LC parallel resonance circuit A is stably resonated by this feedback. When the Q value of the LC parallel resonance circuit A is changed by the atmospheric temperature, corresponding to this change, the loop gain is controlled by the temperature compensating circuit E and as the result, the loop gain is stablized to the atmospheric temperature. Thus, a distance to detect the presence/absence of a coin is prevented from being changed by the temperature change.

Filed: 1986-08-06
Abstract: PURPOSE:To limit the color removal of a chrominance signal due to a comb line filter to a minimum without increasing the length of a delay circuit by using the correlation detection of a luminance signal. CONSTITUTION:When an output of no correlation is outputted by the first detecting circuit 7 for detecting the correlation characteristic between the lines of the luminance signal, a control circuit 20 brings the output of a limiter 14 to 0, stops the operation of a recurrent filter 18 and inputs 0 to the 1H delay circuit 12 of the chrominance signal.

Abstract: PURPOSE:To remove deposits in a shaft sealing device to be used in a turbo compressor by providing a pressure equalizing gas pipe to put a head tank for supply of the shaft sealing liquid in communication with a pressure equalizing gas chamber and thereby increasing the amount of shaft sealing liquid temporarily. CONSTITUTION:If one of the valves 22a, 22b is closed and the opening of variable throttle mechanism 23a or 23b on this closed valve side is enlarged, the pressure equalizing gas chamber 4 on the same side is given the same state as released to the atmosphere, so that gas pressure in the pressure equalizing gas chamber 4 will sink. Accordingly, the amount of shaft sealing liquid flowing through the gap between the seal ring 7 and shaft 1 is increased by the gas pressure in the pressure equalizing gas chamber 4 on the other side. Thus foreign matters which have deposited in this gap can be removed.
